Sunglint on Reservoir of Engineer Sérgio Motta Dam, Brazil

Sunlight reflecting off the surface off the reservoir created by the Engineer Sérgio Motta Dam gives the lake a bright whitish-silver color. The sun glint also highlights the contours and irregular shoreline of parts of the reservoir. The dam, formerly known as the Porto Primavera Dam, is an embankment dam on the Paraná River near Rosana in São Paulo, Brazil. It was constructed between 1980 and 1999 for hydroelectric power production, flood control and navigation. At 11.380 km (7.071 mi) in length, it is the longest dam in Brazil. The 22 m (72 ft) tall dam creates a reservoir with a 19.9 km3 (4.8 cu mi) capacity and surface area of 2,250 km2 (870 sq mi).
